They couldn't pinpoint it exactly, just run test and rule that out as they went...
They did lung x-ray and found nothin, no COPD or anything like that...
Then lots of heart tests and couldn't find anything wrong, except for the last test the echo gram showed some water around my heart... I passed all of the other heart tests with flying colors...
My hemoglobin was at 8.5 most of the time, then one test it was 8.1, then they gave me an iron IV and it went up to 8.7 and I started feeling better....
So they finally sent me home yesterday and recommended iron supplements to help get my hemoglobin up...
